The number of vertebrae in the human vertebral column is
Answer Details
The human vertebral column, also known as the spine or backbone, consists of a series of bones called vertebrae. These vertebrae are stacked on top of each other and are categorized into different regions. There are a total of 33 vertebrae in the human vertebral column.
Here's a simple breakdown:
7 cervical vertebrae: These are located in the neck region. The first two are known as the atlas and axis, which are specialized to allow for head movement.
12 thoracic vertebrae: These are located in the upper and mid-back, connecting to the ribs and forming part of the thoracic cage.
5 lumbar vertebrae: These are found in the lower back and are the largest and strongest, supporting much of the body's weight.
5 sacral vertebrae: These are fused together to form the sacrum, a triangular-shaped bone at the base of the spine, which forms part of the pelvis.
4 coccygeal vertebrae: These form the coccyx or tailbone, and are usually fused together.
Therefore, when you add up these vertebrae (7 cervical + 12 thoracic + 5 lumbar + 5 sacral + 4 coccygeal), you get a total of 33 vertebrae in the human vertebral column. It's important to note that while the sacral and coccygeal vertebrae are often fused together, they are still counted separately when totaling the number of vertebrae.
